2 Claims, 8 Drawing Figures 65 I I I4 BOTTLE VALVE BACKGROUND OF THE INVENTION The present invention relates to a bottle valve and more particularly to such a bottle valve which is adapted to be readily adjusted between a position in which the contents of the bottle on which the valve is mounted can be accurately poured therefrom and a position in which the bottle is sealed so as to preclude access of deleterious matter to the contents of the bottle as well as to preclude evaporation therefrom.

It has long been known as advantageous to attach a pouring spout to a receptacle such as a bottle, can, or the like to assist in pouring. Such a pouring spout possesses particular utility where the contents of the bottle on which it is mounted is expensive or in some way dangerous such as in the case of liquor or chemicals. The pouring spout minimizes spillage during pouring by accurately directing the flow from the bottle.

Conventional. pouring spouts are deficient in a number of significant respects. Most conventionally available pouring spouts do not allow closing of the spout when not in use. Thus, insects, dust and other deleterious matter can and often do gain access to the bottle, thereby contaminating its contents. Furthermore, particularly where only small quantities of the contents are used over a prolonged period of time, the loss due to evaporation is a problem.

A few conventional pouring spouts have a gravitationally positioned flap at the end of the spout for obstructing the spout when not in use. However, such flaps do not effectively seal the bottles since they are only gravitationally positioned and often do not fit properly. Furthermore, such spouts are mounted on the bottles only by being pressure fitted into the throat of the bottle. Over a long period of use, the spouts frequently loosen, increasing the risk of leakage, contamination and evaporation.

Therefore, it has long been recognized as desirable to have a bottle valve which permits selective opening and closing of an associated spout to permit sealing of the contents of the bottle from contamination and evaporation as well as to faciliate pouring of the contents from the bottle.

DESCRIPTION OF THE FIRST EMBODIMENT Referring more particularly to the drawing, the bottle valve of the first form of the present invention is generally indicated at 10. As shown in FIG. 1, the valve is intended to be mounted on a bottle 11 having an upper threaded end 12 with a circular rim l3 defining a port or pouring opening 14.

The bottle valve 10 includes a body generally indicated at 20 in FIG. 5. The body has a first plate 21 having parallel upper and lower surfaces 22and 23, respectively, and a circular periphery 24. A substantially cylindrical air tube 30 extends into the bottle 11 from the lower surface of the plate parallel and eccentric to the axis defined by the plate, as best shown in FIG. 4. The air tube has an internal passage 31 which c0mmunicates with the upper surface of the first plate through an air opening 32. The tube has :an air inlet 33 at the other end thereof. v

. A pouring opening 40 of somewhat larger diameter than the air opening 32 is provided in the first plate 21 interconnecting the upper and lower surfaces 22 and 23, thereof. The opening defines an axis eccentric to the axis defined by the plate. An arcuate cam way 41 is provided in the upper surface of the plate defining a path of travel concentric to the plate. The cam way is positioned with one end thereof in alignment with the air opening and pouring opening of the plate and the other end thereof therefrom along an arcuate path of travel, as best shown in FIG. 2. A gasket 42, having an outer diameter slightly larger and concentric to the first plate, is adapted to be positioned on the lower surface of the plate, as will subsequently be described.

A closure or head is mounted on the body 20 as generally indicated at 50 in FIG. 4. The head has a second plate 51, having upper and lower surfaces 52 and 53,

respectively. A pouring spout 54 having a discharge passage 55 extending therethrough is coextensively mounted on the upper surface of the plate eccentric to the axis defined by the plate. The discharge passage communicates with the lower surface of the plate at a position corresponding to that of the pouring opening 40 of the first plate 21. An air orifice 56 is provided in the second plate interconnecting its upper and lower surfaces in a position corresponding to that of the air opening 32 of the first plate. A cam follower 57 is mounted on the lower surface of the plate. The second plate is mounted on the first plate with the lower surface of the second plate in facing engagement with the upper surface of the first plate and with the cam follower received in the cam way '41. A lever arm or wing 58 is mounted on the pouring spout substantially tangential thereto. The second plate extends radially outwardly of the wing and spout to form a flange 59.

A substantially cylindrical cap is shown generally at 65 in FIG. 4. The cap has an internally screw-threaded portion 66. The other end thereof has an inwardly bent lip 67 which defines a central spout opening 68. When the bottle valve is in its assembled configuration, the cap is received about the pouring spout 54 and wing 58 of the head 50 with the lip rested against the flange 59 of the second plate 51. The first plate 21 is received against the lower surface 53 of the second plate and the gasket 42 is received against the lower surface 23 of the first plate about the air tube 30, as best shown in FIG. 4.

DESCRIPTION OF THE SECOND EMBODIMENT The bottle valve of the second form of the present invention is generally indicated at 100 in FIG. 6. As shown in FIG. 6, the valve is mounted on a bottle 10! having an upper end 102. It will be seen that the bottle valve of the second form of the invention does not require the use of existing external threads at the upper end of the bottle. Therefore, the bottle shown does not possess such threads although they would not interfere with use of this form of the valve. The upper end of the bottle has a rim 103 which defines a pouring opening 104 for the bottle.

The valve 110 has a body generally indicated at 120 in FIG. 6. The body consists essentially of a substantially cylindrical spout or pouring portion 121 and an opposite plug portion 122. The pouring portion of the body has a sealed end 123. The body defines an internal passage 124 having a pouring opening 125 adjacent to the sealed end and an entrance opening 126 at the opposite end of the body.

An air tube 130 is coextensively mounted within the internal passage 124 of the body 120 extending parallel to the axis defined by the body. The tube has an internal passage 131 communicating with the exterior of the body through an air opening 132 in the pouring portion of the body. The tube has an air inlet 133 at the other end thereof outwardly of the entrance opening 126 of the body. 1

A central flange 140 extends radially from the body 120 intermediate the pouring portion 121 and plug portion 122 thereof. An end flange 141 extends radially from the plug portion of the body about the entrance opening 126. A resilient sleeve 142 of rubberized material having a stop flange 143 radially extending therefrom at one end thereof is fitted about the plug portion of the body between the central and end flange, as best shown in FIG. 6. A pair of grooves 144 are provided in the periphery of the pouring portion of the body extending arcuately in opposite directions from positions in alignment with the pouring opening 125 and air opening 132, as best shown in FIG. 8.

The bottle valve has a substantially cylindrical closure generally indicated at 150 in FIG. 6. The closure defines an internal passage 151 having a diameter equal to or slightly larger than that of the external periphery of the body 120. The closure has a sealed end 152 and a bearing flange 153 radially extending from the end thereof opposite that having the sealed end. A pair of followers 154 are integrally provided on the closure extending inwardly of the internal passage in predetermined positions adjacent to the bearing flange. The closure affords a discharge opening 155 in a position corresponding to that of the pouring opening of the body. An air orifice 156 is provided in the closure in a position corresponding to that of the air opening 132 of the body. The axes defined by the opening and orifice are in alignment with a line defined by the followers. The closure is received in covering relation about the pouring portion 121 of the body with the followers received in the pair of grooves 144 of the body.

OPERATION The operation of the described embodiments of the present invention is believed to be clearly apparent and is briefly summarized at this point. Although there are significant structural distinctions, the bottle valves 10 and 110 of the present invention operate in substantially the same manner. The valve 10 is particularly adapted for use on a bottle 11 having an upper threaded end 12. The valve 10 is mounted on the bottle by positioning the body 20 on the rim 13 of the bottle with the gasket 42 disposed between the lower surface 23 of the body and the rim of the bottle. Thus, the air tube 30 extends inwardly of the bottle. The head 50 is mounted on the upper surface 22 of the body with the cam follower 57 received in the cam way 41 as previously described.

The screw-threaded portion 66 of the cap 65 is then threadably secured on the upper threaded end 12 of the bottle so that the lip 67 of the cap is drawn downwardly against the flange 59 of the head 50. The resilience of the gasket 42 allows the cap to be tightened to the extent desired so as to control the ease of rotational movement of the head with respect to the body. Such tightening of the cap secures the gasket in fluid-tight sealing relation against the rim so as to preclude the leaking of the contents of the bottle between the rim and the gasket or between the first plate 21 and the second plate 51. So mounted on the bottle, the valve 10 is ready for use.

The bottle valve 110 is intended for use on virtually any bottle and is not dependent on the use of threads for attachment as in the first form of the invention. The valve 110 is mounted simply by pressure fitting the plug portion 122 of the body 120 within the pouring opening 114 of the bottle 111 until the stop flange 143 of the sleeve securely contacts its rim 113, as shown in FIG. 6. So mounted, the air tube thereof extends inwardly of the bottle. The secure engagement of the resilient sleeve in the pouring opening insures that no leakage can occur between the rim and the stop flange thereof. When mounted in the bottle as described, the valve 110 is ready for use.

The valves and 110 are sealed for storage in substantially the same manner. In the case of valve it), the head 50 is simply pivoted until the discharge passage 55 and air orifice 56 no longer communicate with the air opening 32 and pouring opening 40 respectively in a closed position designated by the follower 57 reaching the end of the cam way 41. In the case of valve ll it), the closure 150 is rotated about the pouring portion 121 of the body 120 until the passage R and orifice 156 no longer communicate with the pouring opening i125 and air opening 132 of the body respectively. Thus, a closed position is reached, as designated by the followers 15 reaching the ends of the grooves 144.

In order to pour contents from the bottle Ill on which the valve 10 is mounted, the head 50 thereof is rotated 90 from the closed position to an opened position as designated by the cam follower 57 reachingthe other end of the arcuate cam way 411. The pouring spout 54 and the air orifice 56 are thereby rotated a corresponding 90 so that they fully communicate with the pouring opening 40 and air opening 32, respectively. The bottle is then simply tilted in the conventional manner to allow the contents of the bottle to pass through the upper threaded end 12 thereof, the pouring opening, the discharge passage 55, and out through the pouring spout 54. A smooth flow of fluid is insured by ambient air being drawn through the air orifice 56 and the air tube 30 into the interior of the bottle to displace fluid discharged through the pouring spout.

The bottle valve 110 is made operable in a similar manner by rotating the closure 150 90 from the closed position to an open position as designated by the followers 154 within the pair of grooves 114d. Thus, the discharge opening 155 and air orifice 156 thereof communicate with the pouring opening 125 and air opening 132 of the body. Thereafter, the bottle Mill is simply tilted in the usual manner to allow the contents of the bottle to pass through the entrance opening H26, the internal passage 124 and outwardly through the pour ing opening and discharge opening. As with the bottle valve 10, the flow of contents from the bottle is facilitated by the admission of ambient air through the air orifice 156 and air tube 130 to displace the contents of the bottle during discharge therefrom.

it will be noted that with both of the valves W and 110 the head 50 and closure 150 respectively can be rotated less than the maximum 90 so that the discharge of the contents from the bottles ill and llli respectively can be effectively regulated or limited. Similarly, both valves 10 and 110 are closed when desired by rotating the head and closure respectively back to the closed positions for storage. In the case of bottle valve 10, the cap 65 can be tightened down on the threaded end 12 of the bottle after use to prevent inadvertent'rotation of the head until the cap is again loosened for pouring.

Therefore, it will be seen that the bottle valves it and 11 0 of the present invention facilitate the pouring from t bottles on which they are mounted. The valves also permit sealing of the bottles so as to preclude the possibility of deleterious materials gaining access to the contents of the bottles and simultaneously preventing evaporation of the contents from the bottles during storage.

Although the invention has been herein shown and described in what are conceived to be the most practical and preferred embodiments, it is recognized that departures may be made therefrom within the scope of the invention, which is not to be limited to the illustrative details disclosed.
